Abstract: A composition for promoting bacterial proliferation and selectively proliferating Lactobacillus casei subsp. casei is disclosed, which includes a dextran. A variety of biological activities originating from L. casei subsp. casei can be sustained in a living body by selectively growing-proliferating and colonizing L. casei subsp. casei in the intestine of a human being, animal, or the like or by selectively growing-proliferating L. casei subsp. casei in the intestine, without supplying L. casei subsp. casei at all times.

Abstract: The present invention provides a polysaccharide-magnetic metal oxide complex consisting of a polysaccharide derivative obtained by carboxyalkyl-etherifying and unsubstituted or substituted aminoalkyl-etherifying a polysaccharide (the above carboxy group and/or amino group may be of a salt form) and a magnetic metal oxide. The above complex has a slow blood clearance and a low toxicity and is useful as a nuclear magnetic resonance imaging contrast medium.

Abstract: A water-soluble carboxypolysaccharide-magnetic iron oxide complex of small particle diameter composed of a water-soluble carboxypolysaccharide and a magnetic iron oxide having a core diameter ranging from about 2 to about 7 nm, wherein the total diameter ranges from about 10 to about 50 nm, the ratio of the total diameter to the core diameter is about 15 or less, and the T.sub.2 -relaxivity ranges from about 10 to about 150 (mM.sec).sup.-1. Said complex has low toxicity and small side effects and is useful in the fields of medical treatment, biology and engineering as an iron-supplementing agent, an X-ray contrast medium, an MRI contrast medium, a reagent for blood flow rate measurement, a carrier for drug administration, etc.

Abstract: A yarn unevenness information analyzing apparatus which can perform an analysis of periodic yarn unevennesses without being restricted by another analysis of non-periodic yarn unevennesses. Signals from a large number of yarn evenness detectors are inputted to a CPU for yarn unevenness analysis by way of a first switch for changing over the signals in a short period to successively output the signals and a second switch for changing over the signals in a long period to successively output the signals.

Abstract: An oxidized complex comprising a water-soluble carboxypolysaccharide and magnetic iron oxide, which is characterized by being obtained by oxidizing a complex comprising a water-soluble carboxypolysaccharide and magnetic iron oxide. Said oxidized complex has very low toxicity, is very stable, exhibits little or no blood pressure-reducing action and has low platelets-aggregating action when administered directly into the blood vessels of animals, and is useful in medical fields such as contrast medium for magnetic resonance imaging, exothermic medium for hyperthermia and the like.

Abstract: A composition containing magnetic metal oxide ultrafine particles, which comprises an aqueous sol of a complex of the magnetic metal oxide ultrafine particles with a polysaccharide, a polysaccharide derivative and/or a protein; and an organic monocarboxylic acid. The composition is free of side effects such as platelet aggregation, is safe for use with living bodies, and, in the case of intravascular administration, has no harmful effects on living bodies, and is useful in fields such as medicine and diagnostic drugs.

Abstract: A complex of a carboxyalkyl ether of a polysaccharide with a magnetic metal oxide. This complex is extremely excellent in stability in preservation in the form of aqueous sol and has only a low toxicity, and thus is useful, for example, for medical use as a nuclear magnetic imaging molding agent or the like.

Abstract: A magnetic iron oxide-dextran complex. This novel compound can be produced by reacting an aqueous sol of magnetic iron oxide with dextran having an intrinsic viscosity of about 0.02 to about 0.5 at an elevated temperature in an aqueous medium, and is useful not only in pharmaceutical and medical fields as a hematinic medium, a radiopaque medium, a blood measuring agent, or a carrier for a medicinal substance, but also in wide range of other technological fields where its magnetic property can be utilized.
